RangeError #2006 in Robotlegs Tutorial by Joel Hooks Part2: Models

Hello,
I've made application based on JoelHooks
Models Tutorial and it throws RangeError every time. Because of
this error, theres only one author on a list, instead of four so I
assume, that this error has something to do with AuthorModel.list
and ListView component. I debbuged whole application step by step,
but I hadn't found exact moment, when application failes (which is
odd). Can someone help me fix this problem?
I give my src and libs, if it could help more in solving the
case.
